Radio

In computer science, „Radio“ typically refers to a type of user interface element known as a „radio button.“ Radio buttons are circular selection controls that allow the user to select one option from a predefined set of options. When a radio button is selected, any previously selected button within the same group is automatically deselected, ensuring that only one option can be chosen at a time.

Radio buttons are commonly used in forms and settings where exclusive choices are necessary, such as selecting a payment method or answering a multiple-choice question. They provide a clear and easy way for users to make selections, and their visual design helps to convey the available options effectively.

In terms of functionality, radio buttons are often grouped together within a form element, and each button is associated with a specific value. When the form is submitted, the value of the selected radio button is sent to the server or processed by client-side code. Overall, radio buttons are an essential component of user interfaces, particularly in web and application development.
